[Osteomyelitis of the ilium and traumatic rupture of a hydronephrotic right kidney imitating acute appendicitis].

The author describes two case-histories of profoundly different diseases which imitated in a similar way the symptoms of acute appendicitis. In both instances the authors had to operate under pressure of the local finding, although in the case of osteomyelitis of the ilium this diagnosis was contemplated before operation. The author draws attention to some specific features of work in developing countries.
